'The Amazing Race' new season to reportedly feature entire cast of former 'Big Brother' houseguests

According to sources close to production, The Amazing Race has locked down its lineup of teams for the new season and they've all spent time in the Big Brother house, TMZ reported.

The Amazing Race will allegedly have an all-Big Brother edition, featuring at least one winner of the Big Brother franchise. Several other BB winners, although probably interested in racing around the world, declined the opportunity due to career or family reasons.

The production sources told TMZ that CBS is very happy with The Amazing Race teams they have found to compete.

While The Amazing Race has included several former Big Brother houseguests in prior seasons, the sources said producers got the ball rolling on the idea this year because of the success Jessica Graf and Cody Nickson had on the show last season.

Jessica and Cody, who met on Big Brother's nineteenth edition last summer and joined The Amazing Raceas a dating couple, ending up winning the $1 million on Season 30. The lovebirds also got engaged after they filmed the show in February 2018.
